Slack Micro Client

This is a zero dependency node.js client for Slack's Web API

The goal of this project was to build a node.js client that can be dropped into serverless functions without requiring a massive dependency tree. This client covers two main scenarios: making requests and handling responses.

Install

npm i slack-micro --save

Requests

API

slack('method name or url', {payload}) // returns a promise

Examples

let slack = require('slack-micro');

let message = {
  unfurl_links: true,
  channel: 'C1QD223DS1',
  token: 'xoxb-12345678900-ABCD1234567890',
  text: "I am a test message http://slack.com",
  attachments: [{
    text: "And here's an attachment!"
  }]
}

// send message to any Slack endpoint
slack('chat.postMessage', message).then(result => {
  // Success! The response is in result
});

// respond to webhooks
slack('https://hooks.slack.com/services/T0000/B000/XXXX', message);

Responses

API

// event handler
slack.on('event name', [... 'event name',] callback);

// digester
slack('JSON string' or {message});

Examples

let slack = require('slack-micro');

slack.on('/test', message => {
  // handle the "/test" slash commands
});

slack.on('slash_commands', message => {
  // handle all slash commands
});

slack.on('googlebot', message => {
  // handle the outgoing webhooks trigger word "googlebot"
});

slack.on('googlebot', '/test', 'slash_commands', message => {
  // handle multiple events
});


// AWS Lambda handler
exports.handler = (event, context, callback) => {
  slack(event.body); // parses the body  
}
